I conjecture that this certificate might had been issued when the sextant
was already not new, and an owner brought it to Freiberger for inspection.
Anyway, on the place of your friend I would talk to Freibergers.
I also do not understand how your friend could determine the arc
error himself with such degree of accuracy.
